PUMPING AND MEASURING APPARATUS FOR OIL, Sec.

SPECIFICATION forming part of Letters Patent No. 617,019, dated January3, 1899. Application filed November 28, 1894. SerialNo. 530,262. (Nomodel.)

To @ZZ whom, t may concern:

Be it known that I, GEORGE HOLLAN, a citi- 'zen of the United States,residing in the city and county of Philadelphia, State of Pennsylvania,have invented a new and useful Improvement in Pumping and MeasuringApparatus for Oil and other Fluids, which improvement is fully set forthin the following specification and accompanying drawings.

My invention has for its object an improvement in pumping and measuringapparatus for oil and other iiuids in which a predetermined quantity ofiiuid can be readily elevated and measured and discharged from themeasuring device into a suitable receptacle.

The invention consists of a stand for a can, rbc., of novelconstruction, and, furthermore, of a closed chamber which is connectedwith the drip-pipes of said stand and the pump and the return-pipe tothe barrel, as will be hereinafter set forth, said parts being connectedwith a base, so as to be carried as one and readily located at the placeof service, the can stand or holder being adapted to be interlocked withsaid base.

Figure l represents a side elevation of a pumping and measuringapparatus for oil and other fluid embodying my invention. Fig. 2represents a partial plan View and partial horizontal section ofthe sameon line 2 2, Fig. l. Fig. 3 represents an end view of the same. Fig. 4represents a vertical section of a detached portion. Figs. 5, 6, and 7repre- Sent vertical sections of detached portions on an enlarged scale.Fig. 8 represents a side elevation of a detached portion on an enlargedscale. Fig. 9 represents a horizontal section on line 9 9, Fig. 8. Fig.l0 represents a vertical section of a detached portion.

Similar letters of reference indicate corresponding parts in the severalfigures.

Referring to the drawings, A designates a base, on which is securedapump B, provided with a suction-pipe C, depending therefrom, said pipehaving a check-valve D-and a removable section of pipe E, provided witha check-valve F, the use of said section of pipe E being hereinafterexplained. The pipe O and its removable section E form a communicationbetween said pump B and the source of supply from which the liquid to bemeasured is to be pumped, which is in the present instance a barrel G.

Connected with the pump B is an elbowshaped discharge-pipe H, providedwith a check -valve II', said pipe being also connected with a receiverJ, so as to form a communication between said pump B and receiver J, sothat the liquid pumped from the barrel G Will be caused to enter saidreceiver 6o The vertical portion of the pipe H may also serve as asupport for the receiver J, as shown in the drawings, and it may bestrengthened, if desired, by a brace H2 to prevent said receiver fromshaking when the pump B is operated.

The receiver J consists of a cylinder J', preferably of glass, so thatthe liquid pumped thereinto may be seen through the same. The cylinder Jis closed at the top bya head 7o K and at the bottom by a head L, saidheads being held in position on the cylinder J by rods M, whose lowerends are provided with heads N, (see more particularly Fig. 81,) whichcontact with the under side of the head L and act as supports for thesame. The upper end of the said rods M are screw-threaded at P toreceive nuts Q, by means of which the heads K and L are tightenedagainst the ends of the cylinder J, so as to make tight joints and pre-8o vent the liquid in the receiver J from leaking.

If desired, rubber Washers, cement, tite., may be employed in thesejoints to further insure the receiver J -against leakage.

The head L is formed with an opening R, 8 5 which receives one end ofthe pipe H, and also an opening S, Figs. 6 and 10,which forms a seat forthe plugT of avalve-stem U,which is screw-threaded at V and works in ascrewthreaded opening W` in the head K, Fig. 4, so 9o that by properlyrotating the stem U its plug T may be made to either open or close theopening S in the head L, so as to either retain within the receiver Jthe liquid pumped thereinto or permit the same to escape through theopening S.

The head L is provided on its under side with a chamber or channel X,Figs. d and 10, which communicates with the receiver J by-l means of theaforesaid openingS and has coliloo nected with it the discharge nozzleor pipe Y.

Z designates a vent-hole in the head K to permit the escape of the airin the receiver J which is displaced by the liquid pumped thereinto.

The end of the pipe H which is connected with the receiver J is providedwith a cap A', formed with openings B', through which the liquid pumpedinto the pipe H passes and enters said receiver J in the form of aspray, it being noticed that the cap A' acts as a deiiector for the:fluid which is being pumped and removes any possibility of its beingejected through the vent-hole Z when the pump B is iirst started. (SeeFig. 6.)

C' designates fingers adapted to be raised and lowered independently ofeach other on one of the rods M, Figs. 1, 8, and 9, said tingers beingheld when in adjusted position by screws D', which bind them to the rodon which they slide, the aforesaid lingers C' serving as a gage toindicate the quantity of liquid pumped into the receiver J.

E' designates a drip-pipe which leads from the upper portion of the pumpB to a coupling F', secured to the base A, and E2 designates a drip-pipewhich leads from said coupling to the barrel G, so that in case some ofthe liquid pumped from said barrel should enter the space between thetop of the pump B and its plunger B2 'the same may return through thepipe E', the coupling F', and pipe E2 to the barrel G. The pipe E2 isprovided with a removable section of pipe F2, the object of which willbe hereinafter explained, said section being connected with the pipe E2by a coupling G.

H2 designates a stand provided with a trough or pan J2, in which isfitted a removable shelf or false bottom K', on which may be placed acan L' or other receptacle for the liquid supplied from the receiver J.The shelf K' is formed with openings M' to permit any liqquid which mayenter said trough or pan J2 to strain through-as, for instance, the dripfrom the faucet Y and the drip and overfiow from the can L' to passthrough said openings M' and reach the inclined bottom N of' said troughor pan J2 and be conducted by the same into a drip-pipe P', leading fromsaid trough or pan to the chamber of the coupling F', and through thelatter to the pipes E2 and F2 to the barrel G, (see Figs. 2, 5, and 7,)it being noticed that the chamber of said coupling is closed, so thatthe smell of the fluid therein cannot escape into the apartmentcontaining the same and insects cannot reach said fluid. The falsebottom K' rests on shoulders below the top of the stand, so that saidbottom is sunken, and the can may be seated into said stand and beprevented from displacement, as it is surrounded by the wallof the upperportion of the stand. The inclined bottom N of the stand is below thefalse bottom K', but above the lower end of the stand, the walls of thelatter having vertical recesses therein, so that the stand may straddlethe horizontal portion of the pipe H, which leads from the pump B to thereceiver J of the measuring vessel, and

thus rest on the base A, which supports said pump, it being noticed thatthe coupling or casing F' also rests on said base, so that the entiredevice is carried by said base and may be located adjacent to the upperends of the suction-pipe C and of the drip-pipe E2 and be coupledtherewith, the base having openings therein to receive said pipes C andE2, whereby communication may be made with the barrel G. y

The operation is as follows: Assuming that the liquid to be measured iscoal-oil, the barrel G containing the same is so located relatively tothe pump B that its bung-hole @will be directly below the pipe C of saidpump. In practice the barrel is usually placed in a cellar and the pumpon the floor above. After the bung has been removed the end of thesection of pipe E to which the check-valve F is secured is passedthrough the bung-hole a and lowered into the barrel G, and its upper endis brought in line with the pipe C and screwed into the check-valve D ofsaid pipe, thereby forming a continuous connection from the barrel G tothe ump B. One end of the section of pipe F is passed through the bunghole d, and its threaded end is brought in line with the pipe E,and thecoupling G' is then rotated, so as to connect both pipes E' and F2, andthus form a continuous connection from the trough or pan J2 to thebarrel G. When it is desired to drawa predetermined quantity of oil fromthe barrel G, the pump B is operated in any suitable manner, and at eachupstroke of its piston some of the oil from the barrel G is drawnthrough the check-valves F and D and the pipes Eand Cinto the pump B.Each downstroke of the piston B2 will cause the oil in the pump B andpipes O and E to close the valves D and F and prevent the oil fromescaping at these points. The pressure upon the oil in the pump B andpipes C and E caused by the downstroke of the piston B2 opens thecheck-valve H' and forces the oil through the same into thedischarge-pipe H and finally into the receiver J. The pumping iscontinued until the oil in the receiver J reaches the linger C'corresponding to the quantity desired. The pump is then stopped and thestem U rotated, so as to cause its plug T to leave the opening S andpermit the oil in the receiver J to flow through said opening and bedirected by the nozzle Y into the can L'. Any drip or overflow from thecan L or the pump B will be conducted by the pipes P' and E' into thecoupling F', and thence to the barrel G, as has already been explained.

Y Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

A base, a pump thereon, a measuring vessel, a conveying-pipe of elbowform having its horizontal limb connected with said pump and passingover said base and its vertical limb supporting said vessel, acan-holder and IIS at the inlet openings thereof and a returnpipeconnected with said chamber at the outlet-opening thereof, said partsbeing combined forming an improvement in a oombined pumping andmeasuring apparatus.
